Why the 6.55 GB releases?

[martixy]

Can someone please explain to me that file size?

I've seen a hell of a lot of releases that weigh in at 6.55GB, yet that exact size does not align neatly with any storage media I am aware of.
There has to be a reason though, it can't all be just a coincidence.

I don't understand what you're asking.

Are you talking about DVD-Rips? Blu-Ray rips? First of all, the better the picture, the bigger the size.

And what about the storage media that "you're aware of?"

I don't want to sound like an asshole, but I'm rather slow on understanding some questions.

[shirepirate]

doesn't ring a bell. are they all from a particular uploader? give examples.

You must have noticed there are certain standard sizes in which files come in. There is a reason for that.

One that has nothing to do with either content or uploader. But rather with being able to utilize the entirety of all available space on non-rewritable storage media. I'm sure you can see the benefit of that.

Here's an example for you: Optical media. Disks.
DVD - 4.37 GB
Double layer DVD - 7.95 GB
CD - 700 MB
A lot of releases are either of that size or a proper fraction of it - like half a DVD, a third, etc.

I hope that brings the point across. Otherwise I'll have to bust out the charts.

We all know that there are certain file sizes which are common, and that the reason for them is based on physical media.

What RobertX and shirepirate are confused about is your claim that 6.55 GB is one of those common sizes. Like them, I've not noticed any such trend.

Post a few links to these mysterious torrents so we can see wtf you're talking about.


EDIT. Browsing back through the HD Movies category it does seem that 6.5 crops up a little more often than one would expect. [I wouldn't go so far as to say "a hell of a lot" but...] And I can't think of any particular reason for it. Weird.

High Definition x264 Standards Revision 4.0 :: 2011-01-29

[ Total Size ]
7.1) Final mkv file size in MiB (1048576 bytes) must be:
Multiples of 1120
DVD5/x (896, 1493, 2240, etc.)

DVD5 = 4480 MiB = 4 x 1120 MiB

6.56 GiB is 1.5 DVD5

You can fit 2 such movies in 3 DVD5 if you split them with mkvmerge.

Anyways, that made sense a few years ago but with external HD as basic storage media you don't need to hit a filesize any more.

My guess is you soon you can expect CRF (just like SD scene releases) at HD instead of 2pass therefore random size.

Finally a reason to this madness. Thank you!

My OCD sensibilities are now satisfied.
